Peru Election 2026: Sánchez Confirms Second Round vs Keiko, Sues Authorities

The closest second-round qualification race in Peruvian electoral history is now likely settled. The left-wing Sánchez candidacy will face Keiko Fujimori for the third time in fifteen years — but this time with López Aliaga’s far-right calling the result “criminal” and the country’s logistics infrastructure under criminal investigation.

The Rio Times, the Latin American financial news outlet, reports that the Peru election has effectively narrowed to its expected runoff matchup. Roberto Sánchez of Juntos por el Perú told reporters on Saturday April 25 that he is “totally convinced” he has secured second place and will face Keiko Fujimori in the June 7 second-round vote.

“As citizens, we are totally convinced, calm, that we are already in the second round, and now comes that great call to refound our homeland with the popular forces,” Sánchez said in a press conference. He demanded “speed and sacred respect for the popular will” from the electoral authorities still finalising the count.

The Peru election count and Sánchez’s path to the runoff

At 95.89% of acts processed by the National Office of Electoral Processes (ONPE), Fujimori sits in first place with 17.063% (2,750,167 votes). Sánchez follows in second with 12.047% (1,941,789 votes). Rafael López Aliaga of Renovación Popular comes in third with 11.94% (1,917,718 votes) — a margin of roughly 24,071 votes behind Sánchez.

Approximately 3,811 actas remain pending at the Jurados Electorales Especiales (JEE), the regional bodies that resolve disputed ballot reports. The JNE’s spokesperson Jorge Valdivia told local media that final official results will not be available until approximately May 15, due to the volume of contested actas exceeding 20,000.

Sánchez’s path to second has been unusual. He started election night ranked sixth and rose progressively to third by April 15, then to second over the following days as rural and southern Peru votes were tabulated. Renovación Popular’s strongest support came from urban Lima; Sánchez’s came from the southern Andean departments and from Peruvian voters abroad.

The Monday lawsuit Sánchez announced

Sánchez confirmed that his bancada will present two constitutional complaints in Congress on Monday April 27 — one targeting the Junta Nacional de Justicia (JNJ) and another targeting the Jurado Nacional de Elecciones (JNE).

The legal grounds focus on the resignation of former ONPE chief Piero Corvetto, which the JNJ formally accepted despite Peruvian electoral law explicitly prohibiting the mid-process replacement of the ONPE head. “There are more than enough grounds for a constitutional complaint,” Sánchez said.

Bernardo Pachas Serrano was named the new ONPE director after Corvetto’s exit. Sánchez has also flagged the broader logistical failures of the April 12-13 vote, including the late distribution of electoral materials by a contractor that had already been penalised three times for similar failures.

EU observers and Peruvian institutions reject fraud claims

The European Union Election Observation Mission has explicitly rejected the fraud allegations being pushed by López Aliaga and his Renovación Popular allies. The EU mission described the process as “peaceful” despite the logistical failures and confirmed it found no evidence of irregularities in counting or tally-sheet transmission.

Asociación Civil Transparencia, the dominant domestic election-monitoring organisation, reached the same conclusion. The Defensoría del Pueblo — Peru’s national ombudsman institution — stated there are “no factual or legal grounds” to allege fraud.

López Aliaga’s response has escalated rather than moderated. He has called the count a “criminal act against the vote” and “electoral sabotage”, offered 20,000 Peruvian soles (US$5,700) to anyone providing evidence of irregularities, and made widely-criticised threats against JNE chief Roberto Burneo. Fujimori herself — strategically allied with the far-right — has called on López Aliaga to either present evidence or stop undermining democratic stability.

What the runoff matchup means for the Peru election

A Sánchez-Fujimori second round on June 7 reproduces the structural divide of recent Peruvian elections: a left-wing candidate against a Fujimorist standard-bearer. Sánchez’s party Juntos por el Perú is contesting the 2026 election as the formal political vehicle of imprisoned former president Pedro Castillo, who was sentenced to more than 11 years for his failed 2022 self-coup attempt.

Sánchez confirmed he would pardon Castillo if elected. The pardon commitment is consequential — it formalises the political debt of the leftist coalition to Castillo’s base, particularly in southern Peru, which delivered the votes that pushed Sánchez ahead of López Aliaga in the final week of tabulation.

Fujimori’s third presidential candidacy faces a structural challenge. She has lost three previous runoffs by narrow margins. The 2026 contest reproduces that dynamic, but with two material differences: López Aliaga‘s far-right base may not consolidate behind her despite their alliance, and Castillo’s pardon promise gives Sánchez a clear left-wing organising frame Fujimori has not faced before.

What to watch in the Peru election runoff cycle

Three variables will define the next six weeks. The first is the JNE proclamation.

Until the JEE finishes resolving the contested actas — expected by mid-May — neither Sánchez nor anyone else is officially confirmed in second place. A López Aliaga reversal, while statistically unlikely, is not procedurally impossible.

The second is López Aliaga’s response. His public threats, calls for “insurgency,” and now the offered 20,000-sole bounties for fraud evidence have already triggered potential criminal investigations. How Renovación Popular’s base actually responds to a confirmed Sánchez second-place finish — whether quietly or with the unrest López Aliaga has invited — will set the tone of the runoff campaign.

The third is the F-16 file. As the Rio Times reported on the FAP crisis, the air force accelerated its US$3.5 billion Lockheed deal in response to Sánchez’s rise. The intersection of an electoral process, a narrowly-won second place, and an accelerated US weapons procurement is unusual — and the political cost of that procurement decision will be visible in the runoff campaign.

For investors and observers tracking Peru, the June 7 runoff now represents the highest-stakes election the country has held in five years. Either Sánchez wins and pardons Castillo, anchoring Peru’s first centre-left government since the 2021-2022 Castillo administration, or Fujimori wins and ends two decades of failed candidacies.

Both outcomes reset Peruvian politics fundamentally. Both will be decided by the votes of citizens whose first-round experience was defined by logistical failures, formal complaints, and a barrage of unsubstantiated fraud claims that the country’s electoral institutions have already rejected.
